4 Claims.

The object of my invention is to provide a winding machine in which packages of flshline, twine, thread, ribbon, or the like, may be progressively wound on adjacent core sections of a single core by means of a plurality of guides spaced along a traverse bar, or by a single guide carried on said bar.

A further object of my invention is to provide means for looking a guide out of frictional contact with the core, or completed package, in an inoperative position in order to prevent wear'on the core, or package, during the winding of subsequent packages.

My invention comprises, generally, a rotary core support, a reciprocating traverse bar, a core removably held on said core support, as a tube circumferentially weakened at predetermined intervals, a plurality of line guides, or a single guide on said traverse bar for use in winding successive packages, and a line supply, said guides or guide being positioned to lead the line from the supply to successive core sections.

Practical embodiments of my invention are 25 shown in the accompanying drawings, in which:

Fig. 1 represents a front elevation of so much of a winding machine as will give an understanding of my invention, in which a plurality of guides are mounted along a traverse bar to pro- 30 gressively wind a separable multiple package unit, shown herein as partially wound;

Fig. 4 represents a detail front elevation of a portion of another embodiment of my invention in which a single guide is mounted on a sleeve, said sleeve being adjustably mounted along the 45 traverse bar;

Fig. 5 represents a transverse vertical section of the embodiment shown in Fig. 4, and shows the guide locked out of frictional contact with the completed package; v

50 Fig. 6 represents an elevation of two packages separated from a completed multiple package unit;

Fig. 7 represents a front elevation of another form of my invention in which manual mears for s5 presenting successive core sections in position for progressively winding packages thereon by the use of a single guide is shown;

Fig. 8 represents a detail front elevation, partly in section, of a means used to adjustably hold the core on the rotary core support;

Fig. 9 represents a detail front elevation, partly broken away, of another means of holding the core on: the rotary core support: and- Fig. 10 represents a transverse vertical section of the core holding means shown in Fig. 9, taken 10 on the line X-X of Fig. 9, looking in the direction of the arrows.

A hollow core I, inthe present instance a cylindrical tube being weakened circumferentially at predetermined intervals as by perforations 2, is removably held on a rotary tube support, as a sleeve 3, having radially projecting wings 4, said support being fixed on shaft 5.

Tube 8 is removably held on said support between a collar 6 on shaft 5 and a washer 1 held in contact with tube I by means of a lock nut 8 adapted to receive the thread of screw 9 which is formed integral with anend of shaft 5.

Shaft 5 is rotatably supported in frame in and may be driven by any well known or approved means, such as a gear 5".

Also rotatably supported in frame it is a shaft H on which a traverse cam 82 is mounted, said shaft II being driven in any well known or approved manner, as, for instance, by the gear a I III A frame I3 is mounted on casing ii" of shaft ll, said frame being adapted to slidably support and guide a traverse bar H.

In the embodiment shown in Fig. 1, a plurality of guides l5 are carried by and swingably mounted on traverse bar I4, said traverse bar being actuated by the travel of a stud or roller l6 aflixed thereto as said stud or roller travels in the endless groove 11 of traverse cam l2.

Frictional contact of the guides IS with their respective packages is maintained by means of a tension device, in the present instance, weights l8 suspended on lines l9 led over pulleys 20. Said pulleys 20 are mounted to rotate on rod 2| which is supported in. arms 22 of frame l3. Said lines l9 are attached at the other ends thereof to eyes 23 on the guides It.

Means for locking the guides l5 out of contact either with the completed package or the core in 5 an inoperative position includes a bracket 24 carried by traverse bar I4, and fixed thereon: by means of set screws 25. Said bracket is located to engage notches 26 in latch levers 2l pivoted at 28 on guides I5 to lock said guides.

In the form shown in Fig. 4, a single guide I5 is swingably mounted on a sleeve 29 between a shoulder 30 on said sleeve and a collar 3|, said collar being fastened to said sleeve by means of a set screw 32. Sleeve 29 is adjustably fastened along traverse bar M by a set screw 33.

Means for maintaining the guide l5 in frictional contact with the package comprises, in this embodiment, an arm 3 afllxed at an angle to guide l5 and carrying a counterbalance, as an adjustable weight 35, held thereon by means of set screw 36. The increase in diameter of the package causes the leverage on arm 34 to increase as weight 35 is caused to swing upwardly as the guide I5 is forced outwardly, thus constantly increasing the pressure of the guide on the package.

Means for locking the guide out of frictional contact with the core or package comprises, in this instance, a bent arm 31 carried by sleeve 29, and located to engage the notch 26 in latch lever 21 pivoted at 28 on guide IS.

A single feed supply roll 33 is mounted in any well known or approved manner, and the line or other material is led therefrom to a guide l5.

To produce a progressively wound separable multiple package unit according to Fig. l, the operation is as follows: I

Look nut 8 is unscrewed, washer I removed,

and the perforated tube I is slipped over the .the tube support carried by shaft 5, and to actuate traverse bar M respectively, said traverse bar l4 being actuated by the travel of stud or roller l6, amxed thereto, in the endless groove I! of traverse cam l2 which is fastened on shaft H.

The winding operation is continued until a package containing a desired length of line or other material is completed, as 39.

The guide I5 is then locked out of frictional contact with the package and the line or other material is removed from the locked guide and led to and through the next successive guide which is then unlocked. The winding operation is repeated to produce another package on a core section adjacent the first until the number of packages desired in a unit has been wound.

When the form shown in Fig. 4 is used, the operation for winding the first package is similar to that described above for the form shown in Fig. 1.

Where it is desired to wind the next package, the guide l5 may be locked at the limit of its outward movement. Set screw 33 is then loosened and the sleeve 29 carrying the guide l5 and its locking means is moved laterally along the traverse bar into position for winding the next package. Set-screw 33 is tightened to hold the apparatus in its proper position on the traverse bar and the guide is unlocked.

The frictional pressure of the guide IS on the core, or package, may be varied by changing the amount of weight used on the form shown in Fig. 1, or by adjusting the weight used as a counterbalance shown in Figs. 4 and 5.

when a unit has been completed, the winding operation is stopped and the line or other material leading from the supply thereof is severed. Nut 8 is unscrewed and washer I removed to allow core I and the progressively wound packages thereon to be removed as a unit.

When the form shown in Fig. 7 is used, the core I is removably held on the core support by manually operable means for presenting successive core sections in position for progressively winding packages thereon by the use of a single guide. Said means may comprise a spindle 40 adapted to be expanded at its outer end into contact with the inner surface of said tube I to hold the same thereon, as by forcing the tapered shoulder of screw 4| into the slot 42 of said spindle 10, which spindle is slit longitudinally at 43.

In the form shown in Figs. 9 and 10, the spindle 40 carries a longitudinally disposed blade ll adapted to engage the inner surface of the core I to hold the core thereon.

In the embodiments shown in Figs. '1, 8, 9 and 10, a. package is wound on the outer end of the core and the core is then manually slid outwardly along the spindle until the next sueceeding core section is in position to have the package wound thereon.

This operation is repeated until the desired number of packages have been progressively wound when they may be removed as a unit.

The embodiments shown and described but not claimed herein form the subject matter of my divisional applications filed July 6, 1938, Serial Nos. 217,691 and 217,692.
